Smoldering Systemic Mastocytosis Without Detectable KIT Mutation: A Debilitating Course and Therapeutic Challenge

Cancer Nexus, EarlyView.
Graphical abstract illustrating the clinical course and treatment response. ABSTRACT Systemic mastocytosis (SM) is a clonal hematologic neoplasm driven by activating KIT mutations, particularly D816V. Indolent SM typically follows a stable course, progression to higher‐burden subtypes is uncommon.

Charge State Influence on Stability and Isomerism in Dehydrogenated PAHs: Insights from Anthracene, Acridine, and Phenazine

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
The ionization of anthracene, acridine, and phenazine has been explored, along with the removal of one and two hydrogen atoms, to provide valuable information for astrochemists and to understand the behavior of the resulting structures and their electronic reorganization. Abstract In this study, we systematically explored the stability and isomerism of

Digital Transformation of Medicines Regulation in Africa—Perspectives from a Stakeholder Convening

Clinical Pharmacology &Therapeutics, EarlyView.
Regulatory authorities worldwide are developing strategies to integrate artificial intelligence (AI) into the lifecycle of health products, technologies, and medicines. While regulators share goals of improving efficiency, strengthening decision‐making, and protecting public health, their approaches differ according to institutional structures ...

Characterization of CD123 expression by mast cells in systemic mastocytosis with multicolor flow cytometry

Cytometry Part B: Clinical Cytometry, EarlyView.
Abstract Systemic mastocytosis (SM) is a clonal mast cell (MC) disorder characterized by aberrant immunophenotypes, including expression of CD25, CD2, and occasionally CD30. CD123, the α‐subunit of the interleukin‐3 receptor, is a therapeutic target in hematologic malignancies and has been reported to be expressed on neoplastic MCs by ...
